  If the bulb lights but the field of view is dark in your Olympus Microscope, try these steps: Increase the light intensity to an optimum voltage. Adjust the condenser height until the field iris diaphragm image is formed in the specimen plane and center the condenser so that the field iris diaphragm image is centered in the field of view. Ensure the revolving nosepiece clicks properly into place. Set the light path selector knob to the binocular eyepiece light path position or increase the light intensity. Reduce the number of filters to the minimum required. Move the stage and place the specimen again if the stage center plate is engaged in the light path. Open the field iris diaphragm sufficiently. Set the knob at the middle or pushed-in position if the light path selector knob of the tr...
